How To Extend HP Envy dv4 Series battery Life

1. Use the correct recharging procedure for your HP Envy dv4 Series. Only use the power cord that came with your laptop or an authorized replacement.

2. Follow correct maintenance for your battery when not in use. Don't leave it in direct sunlight, areas where it will be exposed to extreme temperatures such as car trunks.

3. Use your laptop's power management features. The system will run at lower processor speeds when enabling power management features and it will go into "sleep" mode faster when inactive.

4. New Li-Ion battery must be fully discharged and then recharged every 2-3 weeks.

5. If you don't use your laptop for a period of time, you must fully discharge then recharge the HP Envy dv4 Series battery.
